Spent the morning working on some remaining biblio issues that were minor but difficult to fix:

• The format of the "last access" date did not follow Chicago style (in brackets, in US MMM d, YYYY, following the URL. I fixed this. In the process I had to write a template for converting a TEI date format to this rendering.
• Chicago draws a distinction between "public documents" available online, and regular articles on the Web. The former should be unitalicized and unquoted; the latter are quoted. The former are basically, it seems to me, monographical, so I've always marked them up as <title level="m">, so they were being italicized; I'm now marking them with an additional type="WWW_public_document", and the XSLT code takes account of this and renders them without italicization.
• Analytics with no date (e.g. a Wikipedia article with no author, date or monograph/imprint info) were ending up with an extra period after the "author" name (in this case Wikipedia). It took a while to figure out where this was coming from, but once I'd found it, I was able to eliminate it with a test for the existence of the date tag.

All these fixes were then ported over to the XHTML codebase.

As far as I'm aware, we now have no outstanding issues with regard to bibliography rendering.
